Abstract

본 발명은 재생 변조신호 발생장치에 관한 것으로, 특히 비디오테이프레코더(VCR)나 비디오카메라(일명 캠코더)등에 포함되는 비디오신호처리보드를 검사하고 조정하기 위해서 상기 비디오신호처리보드에 기준신호로서 제공할 안정된 재생 변조신호를 발생하시키도록한 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for generating a reproduced modulation signal, and in particular, to provide a reference signal to the video signal processing board for inspecting and adjusting a video signal processing board included in a video tape recorder (VCR) or a video camera (aka camcorder). A device for generating a stable reproduction modulated signal.

본 발명의 기술적은 구성은 주제어부로부터의 제어신호에 따라 각 블록을 제어하는 부제어부; 상기 부제어부의 제어에 따라 복합비디오신호를 발생시키는 비디오신호발생부; 상기 비디오신호발생부로부터의 신호를 기록모드하에서 FM변조하는 데크1; 상기 데크1으로부터의 변조된 고주파신호중에 포함된 노이즈성분을 제거함과 동시에 상기 고주파신호의 레벨을 조절하도록된 레벨조절부; 상기 부제어부의 제어에 따라 재생모드로 동작하여 재생된 비디오신호를 출력함과 동시에 비디오신호처리보드를 정상적으로 신호를 처리하도록 동작시키는 데크2; 상기 부제어부의 제어에 따라 상기 레벨조절부로부터의 출력신호와 데크2로부터의 출력신호중에 하나를 선택적으로 출력하는 스위칭부를 구비한 것이다.Technical configuration of the present invention includes a sub-control unit for controlling each block in accordance with a control signal from the main control unit; A video signal generator for generating a composite video signal according to the control of the sub-controller; A deck 1 for FM modulation of the signal from the video signal generator in a recording mode; A level adjusting unit configured to remove a noise component included in the modulated high frequency signal from the deck 1 and to adjust a level of the high frequency signal; A deck 2 operating in a playback mode under the control of the sub-controller to output a reproduced video signal and to operate the video signal processing board normally; And a switching unit for selectively outputting one of an output signal from the level control unit and an output signal from the deck 2 according to the control of the sub-control unit.
